In a stellarator, nested toroidal magnetic surfaces are created from external magnetic coils, see Fig. 1. Each magnetic field line meanders around on its magnetic surface; it never leaves it.

This creates a toroidal, or doughnut-shaped field ... it produces an oscillating magnetic field, which causes the coil to move in and out over a magnetic core in that same pattern.

Nine of ITER's 18 toroidal field coils, plus a spare, are being fabricated in Europe with the other nine being made in Japan. Gigantic superconducting magnets, they will generate the magnetic cage to ...

Nineteen gigantic toroidal field coils have been delivered to southern France. They will be key components in ITER, the experimental fusion mega-project that will use magnetic confinement to ...

The bundle of magnets at the heart of the U.S. Department of Energy's Princeton Plasma Physics Laboratory's (PPPL) National Spherical Torus Experiment-Upgrade (NSTX-U) is the star of the show.

CFS is working with the tokamak design for its fusion reactor and previously tested the Toroidal Field Model Coil (TFMC ... that the CSMC could create a magnetic field of 5.7 Tesla, about 100,000 ...

Little Big Coil: the record-breaking magnet is the size of a toilet roll core. (Courtesy: Stephen Bilenky/National MagLab) The highest continuous magnetic field ever created in the lab has been ...

Scientists examine the benefits of the double H-coil and single H-coil methods to measure magnetic field strengths with single sheet testers Date: November 14, 2017 ...

A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.
